5 LED (light-emitting diode) headlights (Type II)

7 Background of the invention

9 A conventional headlight mainly comprises a housing, a housing

10 provided tungsten lamp and a glass cover. When using the lighting of the

11 tungsten lamp and the reflection on the inner curved surface of the housing

12, most of the light can be concentrated and emitted forwards. The well-known

13 headlights have the following disadvantages:

is 1. The tungsten lamp has a large volume and occupies a large space in the 16 housing. This reduces the reflection effect of the lighting.

&igr;? 2. The tungsten lamp consumes considerable energy and produces high heat. It is more likely to cause a fire accidentally.

19 3. It is necessary to use an additional transformer to supply the

20 tungsten lamp to light up.

21 4. The tungsten lamp breaks easily and has a short service life.

23 Accordingly, the present invention serves to overcome the disadvantages of the conventional

24 product and specify an LED headlight that has LED and a light

25 bundling cover is used to emit light in a concentrated manner, and the

26 can be used for a long time and consumes little energy.

9 Detailed description of the invention

11 With reference to Figures 1 to 3, the present invention relates to an improvement

12 of a headlight comprising a lamp housing (1), an LED (2), a light-concentrating

13 cover (3) and a cap (4). The lamp housing (1) can be provided with a &eegr; connecting ring (11) in order to be connected to the light-concentrating cover (3)

15. Several holes (12) can be made in the lamp housing (1)

16. The light-concentrating cover is a transparent rigid body and

17 has one side which is a paraboloid (33). An opening (31) is on the bottom of the

is formed cover (3) while a convex surface (32) is formed therein. A

19 Surface (34) is on the top of the cover (3). The LED (2) can be connected to the inside

20 of the opening (31). The cap (4) is mounted on the lamp housing (1)

21 and the surface of the light-concentrating cover (3) is within the central hole

22 (41) of the cap (4). A heat remover (5) is in the housing (1)

23 is provided, which has an annular cavity (51) on its underside for

24 interaction with the connecting ring (11). An IC card (6) is connected to the

25 bottom of the heat remover (5) which is electrically connected to the LED (2)

26. Figure 4 shows an embodiment of the circuit of the IC card (6), which has several

27 transistors D1-D4 to supply alternating current from electric rods

28 (13) on the housing (1) into direct current for the LED (2).

30 In use, when the LED (2) is lit, the light can be concentrated forward, in

31 Arrow direction as shown in Figure 3, due to the light-concentrating cover (3) and its

32 Paraboloid side (33) for effective reflection of the light.

33 Therefore, the LED headlight achieves a perfect lighting effect. At the same time

34 the heat remover (5) directly contacts the IC card (5), which increases the temperature in the

35 housing (1) can be efficiently reduced.

Accordingly, based on the novel embodiment of the present invention which uses the IC card to convert the electric current for easy use of LED and uses the light-concentrating cover to provide a positive effect of concentrating the light, an excellent
Spotlight achieved. This creates improvement and is beneficial.
